Long White Stocking Socks

I am selling a new set of long white stocking socks that came with a costume I ordered and I do not need them. They are unbranded without tags (as they came with a cosplay) but new and unworn, I didn't even bother to try them on so they'd keep that new feeling for the person that buys this. I have no idea what the sizing on these socks would be, but Im guessing a S - XL (American Size) as it came listed as a OS for an Asian company. Listing as NWT even though it doesn't have tags, because, as stated it is still in the original packaging it came in just without tags and unworn.
